#	Implements the "TK" standard file selection dialog box.  This dialog
#	box is used on the Unix platforms whenever the tk_strictMotif flag is
#	not set.
#
#	The "TK" standard file selection dialog box is similar to the file
#	selection dialog box on Win95(TM).  The user can navigate the
#	directories by clicking on the folder icons or by selecting the
#	"Directory" option menu.  The user can select files by clicking on the
#	file icons or by entering a filename in the "Filename:" entry.
